Ne ovat joukko protokollia ja standardeja, joiden avulla eri ohjelmistosovellukset voivat kommunikoida kesken\u00e4\u00e4n internetiss\u00e4. Pohjimmiltaan verkkopalvelut ovat tapa, jolla eri j\u00e4rjestelm\u00e4t voivat keskustella kesken\u00e4\u00e4n riippumatta niiden k\u00e4ytt\u00e4mist\u00e4 ohjelmointikielist\u00e4, k\u00e4ytt\u00f6j\u00e4rjestelmist\u00e4 tai laitteistoista.<\/p>\n<p>Verkkopalvelut perustuvat asiakas-palvelin-malliin. Asiakas l\u00e4hett\u00e4\u00e4 palvelimelle pyynn\u00f6n, ja palvelin l\u00e4hett\u00e4\u00e4 vastauksen. T\u00e4m\u00e4 viestint\u00e4 tapahtuu yleens\u00e4 HTTP-protokollan avulla, joka on sama protokolla, jota verkkoselaimet k\u00e4ytt\u00e4v\u00e4t kommunikoidessaan verkkopalvelimien kanssa. Verkkopalveluissa voidaan kuitenkin k\u00e4ytt\u00e4\u00e4 my\u00f6s muita viestint\u00e4protokollia, kuten SOAP (Simple Object Access Protocol), REST (Representational State Transfer) ja XML-RPC (XML Remote Procedure Call).<\/p>\n<p>Verkkopalveluja k\u00e4ytet\u00e4\u00e4n yleens\u00e4 eri ohjelmistoj\u00e4rjestelmien ja sovellusten integroimiseen. Verkkopalvelun avulla voidaan esimerkiksi <a href=\"https:\/\/thecodest.co\/fi\/blog\/top-programming-languages-to-build-e-commerce\/\">s\u00e4hk\u00f6inen kaupank\u00e4ynti<\/a> sivusto hakea <a href=\"https:\/\/thecodest.co\/fi\/dictionary\/how-to-make-product\/\">tuote<\/a> tietoja toimittajan tietokannasta tai rahoituslaitos p\u00e4\u00e4see k\u00e4siksi varastoon. <a href=\"https:\/\/thecodest.co\/fi\/dictionary\/what-is-the-size-of-your-potential-reachable-market\/\">markkinat<\/a> <a href=\"https:\/\/thecodest.co\/fi\/blog\/app-data-collection-security-risks-value-and-types-explored\/\">tiedot<\/a> kolmannen osapuolen palveluntarjoajalta. Verkkopalveluja voidaan k\u00e4ytt\u00e4\u00e4 my\u00f6s toiminnallisuuksien avaamiseen muille sovelluksille tai mashupien luomiseen yhdistelem\u00e4ll\u00e4 eri l\u00e4hteist\u00e4 per\u00e4isin olevia tietoja.<\/p>\n<p>Verkkopalvelut rakennetaan k\u00e4ytt\u00e4m\u00e4ll\u00e4 erilaisia tekniikoita, kuten XML (eXtensible Markup Language), WSDL (Web Services Description Language) ja UDDI (Universal Description, Discovery, and Integration). XML:\u00e4\u00e4 k\u00e4ytet\u00e4\u00e4n asiakkaan ja palvelimen v\u00e4lill\u00e4 vaihdettavan tiedon muotoiluun. WSDL:\u00e4\u00e4 k\u00e4ytet\u00e4\u00e4n kuvaamaan verkkopalvelu ja sen k\u00e4ytt\u00f6liittym\u00e4, mukaan lukien kutsuttavat metodit ja niiden hyv\u00e4ksym\u00e4t parametrit. UDDI:t\u00e4 k\u00e4ytet\u00e4\u00e4n verkkopalvelujen julkaisemiseen ja l\u00f6yt\u00e4miseen.<\/p>\n<p>Verkkopalvelut voidaan jakaa kahteen laajaan luokkaan: SOAP-pohjaiset verkkopalvelut ja RESTful-verkkopalvelut. SOAP-pohjaisissa verkkopalveluissa k\u00e4ytet\u00e4\u00e4n SOAP-protokollaa asiakkaan ja palvelimen v\u00e4liseen tiedonvaihtoon. SOAP on standardoitu protokolla, joka tarjoaa verkkopalveluille sanomanv\u00e4lityskehyksen. RESTful-verkkopalvelut puolestaan k\u00e4ytt\u00e4v\u00e4t HTTP-protokollaa tietojen vaihtoon. RESTful-verkkopalvelut ovat yleens\u00e4 yksinkertaisempia ja kevyempi\u00e4 kuin SOAP-pohjaiset verkkopalvelut.<\/p>\n<p>Verkkopalveluista on tullut olennainen teknologia nykyaikaisessa <a href=\"https:\/\/thecodest.co\/fi\/blog\/8-key-questions-to-ask-your-software-development-outsourcing-partner\/\">ohjelmistokehitys<\/a>. Niiden avulla eri sovellukset voivat kommunikoida kesken\u00e4\u00e4n, mik\u00e4 on ratkaisevan t\u00e4rke\u00e4\u00e4 integroitujen j\u00e4rjestelmien luomiseksi. Verkkopalvelut ovat my\u00f6s keskeinen tekniikka API:iden (Application Programming Interfaces) luomisessa, joiden avulla toiminnot voidaan avata muille sovelluksille.
